This dissertation is about developing a generic methodology in designing a Biomedical Informatics data/network model for a 911 Call Center. This methodology is generic enough to be utilized for any metropolitan city. If the methodology proposed is successfully implemented, 911 C…
Capital investment reduction, exergetic efficiency improvement and material compatibility issues have been identified as the primary techno-economic challenges associated, with the near-term development and deployment of thermal energy storage (TES) in commercial-scale concentra…
Zinc oxide thin film transistors (TFTs) are investigated in this work for large-area electronic applications outside of display technology. A constant pressure, constant flow, showerhead, plasma-enhanced atomic layer deposition (PEALD) process has been developed to fabricate hig…
The modeling of micromechanical systems (MEMS) under shock conditions can be an extremely difficult task for MEMS engineers. Overall, this field of research is multiphasic nature, since different physical phenomena are strongly intertwined at microscale. This work concentrates o…
Portland-limestone cements (PLC) have been used in practice for a considerable period of time in several countries. In 2008, the CSA A3000 cements committee approved the addition of a new class of cement with up to 15% interground limestone. The CSA A23.1 concrete committee also…
This research finds the optimal power-split drive train for hybrid hydraulic city bus. The research approaches the optimization problem by studying the characteristics of possible configurations offered by the power-split architecture. The critical speed ratio (S_crit) is introd…
Designing dynamic, robust, and static facility layouts are well-known approaches to cope with the stochastic dynamic facility layout problem (SDFLP). A dynamic layout includes an optimal layout in each period of the planning horizon, whereas a robust layout is a good layout over…
Requirement elicitation is one of the most challenging and critical phases of the software development lifecycle. Many faults are introduced into the system as the result of incomplete requirements. An effective approach for the design of software systems is to describe system r…
This dissertation describes the development of tools needed to research how to locate passages with matching meaning in documents written in some ancient language but each later translated into a native tongue. Described are how such endeavors were done in the past as the texts …
The objective of this research effort focused on the evaluation of asphalt mixtures with respect to thermal cracking. Preliminary investigations soon indicated that a fundamental evaluation of thermal cracking was highly dependent upon the more complicated understanding of aspha…
Nevada Department of Transportation (NDOT) is currently experimenting with warm mix asphalt (WMA) technologies and recycled asphalt pavement (RAP). The purpose of this experiment is to evaluate the effects of various WMA technologies and various levels of RAP on Nevada mixtures …
In this thesis, a complex depth-averaged model is developed for simulating heat and fluid flows in vegetated channels, with a capability to simulate dam-break and flooding phenomena. The model is able to simulate both laminar and turbulent flows, it can take the secondary flow e…
Given the amount of electrical consumption associated with living in contemporary society, renewable energy technologies that offer a distributed and cost effective means of generating electricity need to be further developed and researched. Small wind turbines have the capacity…
Traditional terrestrial crops are currently being utilized as a feedstock for biofuels but resource requirements and low yields limit the sustainability and scalability. Comparatively, next generation feedstocks, such as microalgae, have inherent advantages such as higher solar …
The band structure and carrier dynamics of GaAs, GaAs/GaP and InP semiconductor nanowires is explored using a variety of optical spectroscopy techniques including two newly developed techniques called Photomodulated and Transient Rayleigh scattering spectroscopy. The stress and …
Allergy is a disorder of the immune system caused by an immune response to otherwise harmless environmental allergens. Currently 20% of the US population is allergic and 90% of pediatric patients and 60% of adult patients with asthma have allergies. These percentages have increa…
Roadside safety signs are used to inform drivers about different traffic information. These signs play a vital role in traffic safety by influencing drivers’ behavior positively. However, due to limitations of human beings’ on information processing and driver distractions, peop…
Laser surface treatment process, in general, is involved with conduction heating, melting, and superheating in melt phase. In order to gain an understanding of the physical phenomena taking place during laser heating of a workpiece, experimentation and modeling of the process is…
Like many developing economies, the construction industry in Bangladesh is vital to its economic development and growth. However, the Bangladeshi construction industry is plagued by unethical practices, sub-standard construction work, and the inability of local contractors to pa…
